我试图用4张照片创建一个简单的bootstrap carousal。图像正在自动更改 但上一个/下一个控件不起作用。任何建议将不胜感激。这是我的代码：

＆＃13;
＆＃13; 
$('#myCarousel').carousel({
  interval: 2000,
  pause: false
});
＆＃13; 
.carousel-inner > .item > img,
  .carousel-inner > .item > a > img {
      width: 70%;
      margin: auto;
  }

.carousel-fade .carousel-inner .item {
  opacity: 0;
   -webkit-transition-property: opacity;
  -moz-transition-property: opacity;
  -o-transition-property: opacity;
  transition-property: opacity;
}

.carousel-fade .carousel-inner .active {
  opacity: 1;
}

.carousel-fade .carousel-inner .active.left,
.carousel-fade .carousel-inner .active.right {
  left: 0;
  opacity: 0;
  z-index: 1;
}

.carousel-fade .carousel-inner .next.left,
.carousel-fade .carousel-inner .prev.right {
  opacity: 1;
}

.carousel-fade .carousel-control {
  z-index: 2;
}

@media all and (transform-3d), (-webkit-transform-3d) {
    .carousel-fade .carousel-inner > .item.next,
    .carousel-fade .carousel-inner > .item.active.right {
      opacity: 0;
      -webkit-transform: translate3d(0, 0, 0);
              transform: translate3d(0, 0, 0);
    }
    .carousel-fade .carousel-inner > .item.prev,
    .carousel-fade .carousel-inner > .item.active.left {
      opacity: 0;
      -webkit-transform: translate3d(0, 0, 0);
              transform: translate3d(0, 0, 0);
    }
    .carousel-fade .carousel-inner > .item.next.left,
    .carousel-fade .carousel-inner > .item.prev.right,
    .carousel-fade .carousel-inner > .item.active {
      opacity: 1;
      -webkit-transform: translate3d(0, 0, 0);
              transform: translate3d(0, 0, 0);
    }
 }
